f229257f30 You can now manually disable move semantics. 
This may be useful in MSVC to work around a bug described in Trac #10399

53e53171c4 none_t is no loner constructible from literal 0 
This caused problems because:
optional<T> o = 0;
always worked. But often it would create an uninitialized optional.

d4a4cdca1d Supply <string> to fix C++03 compile error on logic_error("...") 
This change makes the library usable (again) on C++03 standard library
implementations where <stdexcept> doesn't imply inclusion of <string>,
e.g. STLport.

5e59e10f93 Fix warnings with gcc 4.4 in C++11 mode 
GCC 4.4 has support for an early draft of rvalue references. When compiling the conforming code it produces warnings such as '../boost/optional/optional.hpp:152: warning: returning reference to temporary'. In order to fix this regression use a special implementation of move(), similar to std::move() on this compiler.

c7cf80e5df Use BOOST_EXPLICIT_OPERATOR_BOOL for optional 
I often have the problem that when I change a std::wstring to boost::optional<std::wstring> and the variable is used as a parameter with Boost.Format, the result silently changes from the string contents to "1".

This change prevents implicit conversion to bool if the compiler supports explicit conversion operators.

e9989b260e Refs #4987. Added forward declaration of namespace-scope swap for boost::optional, this should fix GCC compilation errors. Also swap implementation now uses Boost.Utility.Swap to make use of the workarounds for some broken compilers. If it breaks for your compiler, let me know in the mentioned ticket.
